ABSTRACT
<p><b>OBJECTIVE</b>To extract and identify the chemical constituents of essential oil from Lonicera fulvotomentosa in different collected periods (bud, Silver-flower and Golden-flower periods).</p><p><b>METHOD</b>Extracts in three different collected periods were subjected to GC-MS analysis for determination of their chemical constituents.</p><p><b>RESULT</b>The 29, 34 and 28 kinds of chemical constituents corresponding to the above three periods were found, and 44 kinds of compounds were identified. The relative content of every chemical constituents in each essential oil was obtained by area normalization method.</p><p><b>CONCLUSION</b>The O-tolyl isocyanide was detected from essential oil of Lonicera for the first time. The result indicated that the highest relative content in essential oil in the three periods is alcohol substance and the second is ester and aldehyde. Many common constituents in the essential oil from L. fulvotomentosa, including linalool, hyacinthin, O-tolyl isocyanide, geraniol, methyl anthranilate, and so on, all could be detected in the three periods. However, the differences of their relative content are obvious.</p>
